Sasha Bingham is filming a sequel to "Slowly We Rot", which just happens to be the Floridan death metal legends Obituary's debut album's name, just as Hank Moody's books share names with various Slayer albums.
The name tag on Sasha Bingham's police uniform costume reads Kapinos, an obvious reference to show creator and executive producer Tom Kapinos.
At the end of the episode, Tommy Lee is playing Motley Crue's "Home Sweet Home" with some bar patrons singing along.
Hank refers to "quatloos" when discussing money. Quatloos were the unit of money used in the Star Trek original series 2.16 "The Gamesters of Triskelion".
When Sacha Bingham climbs on top of Hank after they go to her trailer to have her 'dialogue polished' to fool around at the beginning of the episode, her name tag on her shirt says 'Kapinos'. Which is an obvious tie-in to Executive Producer Tom Kapinos.
